This passes locally for me, which fails the overall lit test suite. I
can't debug a passing test, but I will try to help debug the test when
we get some failing logs.

Currently SI_IF results in a s_and_saveexec_b64 followed by s_xor_b64.
The xor is used to extract only the changed bits. In case of a simple
if region where the only use of that value is in the SI_END_CF to
restore the old exec mask, we can omit the xor and perform an or of
the exec mask with the original exec value saved by the
s_and_saveexec_b64.

Summary:
This changes SimplifyLibCalls to use the new OptimizationRemarkEmitter
API.
In fact, as SimplifyLibCalls is only ever called via InstCombine,
(as far as I can tell) the OptimizationRemarkEmitter is added there,
and then passed through to SimplifyLibCalls later.
I have avoided changing any remark text.

This is a better fix than r308708 for the problem introduced in
r304020. It restores the skeleton CU testcases modified by that commit
to their original form and most importantly ensures that
frontend-generated skeleton CUs (such as used to point to Clang
modules) come after the regular CUs. This broke for DICompileUnit
nodes that don't have any immediate children because they are now
constructed lazily instead of the order in which they are listed in
!llvm.dbg.cu. After this commit we still don't guarantee that order,
but we do guarantee that empty skeletons come last.
Shipping versions of LLDB are very sensitive to the ordering of
CUs. I'll track a fix for LLDB to be more permissive separately.
This fixes a test failure in the LLDB testsuite.

Summary: We can use the template parameter `IsPostDom` to pick an appropriate SmallVector size to store DomTree roots for dominators and postdominators. Before, the code would always allocate memory with `std::vector`.

Summary:
This patch moves root-finding logic from DominatorTreeBase to GenericDomTreeConstruction.h.
It makes the behavior simpler and more consistent by always adding a virtual root to PostDominatorTrees.

Summary:
Bash interperets the '?' character as matching an arbitrary character.
On systems that have a file or directory with exactly one character in
their root directory, '/?' gets reinterpreted into that pathname, which
fails to match the expected Help text for llvm-rc.
This patch quotes the '/?' to avoid that edge case.

Summary:
rL257221 attempted to run lit's own test suite continuously, but that
commit was reverted because lit's test suite does not pass on Windows.
Because lit's tests do not run continuously, they often regress.
In order to un-revert rL257221, mark lit tests that fail as XFAIL for
Windows platforms.
Test Plan:
On a Windows development environment, follow the instructions in
utils/lit/README.txt to run lit's test suite:
```
utils/lit/lit.py \
--path /path/to/your/llvm/build/bin \
utils/lit/tests
```
Verify that the test suite is run and a successful exit code is
returned.

Summary:
Whereas rL299560 and rL309071 call `parallelism_groups.items()`, under the
assumption that `parallelism_groups` is a `dict` type, the default
parameter for that attribute is a `list`. Change the default to a
`dict` for type correctness.
This regression in the unit tests would have been caught if the
unit tests were being run continously. It also would have been caught
if the lit project used a Python type checker such as `mypy`.
Test Plan:
As per the instructions in `utils/lit/README.txt`, run the lit unit
test suite:
```
utils/lit/lit.py \
--path /path/to/your/llvm/build/bin \
utils/lit/tests
```
Verify that the test `lit :: unit/TestRunner.py` fails before applying this
patch, but passes once this patch is applied.

Summary:
This reverts rL306623, which removed `FileBasedTest`, an abstract base class,
but did not also remove the usages of that class in the lit unit tests.
The revert fixes four test failures in the lit unit test suite.
Test plan:
As per the instructions in `utils/lit/README.txt`, run the lit unit
test suite:
```
utils/lit/lit.py \
--path /path/to/your/llvm/build/bin \

```
Verify that the following tests fail before applying this patch, and
pass once the patch is applied:
```
lit :: test-data.py
lit :: test-output.py
lit :: xunit-output.py
```
In addition, run `check-llvm` to make sure the existing LLVM test suite
executes normally.
